Tried different monitor (to check that the problem wasn't caused by my monitor) ... still no display.Having the same problem, no display (CPU working tho)

Tried removing the RAM, the system beeps on power up.
Tried reseating the RAM ... no display.
Unplugged all drives (floppy, dvd, hdd) ... no display.

Got the same problem here. Cpu fan runs but no video. I tried unplugging all periferials and no luck. Tried different memory. I am not even getting a beep.Got the same problem here.

I have a similar problem with my Intel mother board D865GLC and it not unbooted and sometimes it will got a blue screen while it was luckily bootup successfully.

I tried to solve this problem in the following steps:1) I cleaned all the dust on my motherboard, especially those resistors hided by the heat sink of the CPU.
(it worked normally again for several weeks and then the motherboard is not so stable, the system are sometimes halted and sometimes the blue screen jump out :-( )
2) Then, I tried to check all the components - RAM, CPU, FAN and Power supply, etc. They seems all OK! but the problems still.
3) I tried to open the case and check the temperature of the board and the problems still.
4) I reinstall the system, but the problem still :-(
5) I am going to give-up; but I think the problem may due to the memory related, because can't bootup with no beep sound and blue screen are the problem of memory.. So, I try again to remove all RAM and using a contact cleaner to clean the RAM slot and the gold contact. The PC work again!!!

Check the connection of your video card, this is the common problem of cpu's specially if you are moving from one place to another. try to uninstall the connector of your monitor to the video card. if you have an extra video card try to replace the existing then power on. loose connection of your video will give you a rapid beep sound. if you are using the on board vga you try to install a video card or try to tighten up the connector.

first make sure your ac cable is working well, then try to check the power supply of your computer if the fan rotates every time you hit the power button of your cpu, if not then change your power supply. if it fan rotates and stops, try to used another power supply if fan rotates and still won't display open up your cpu try to check if the fan over the processor will rotate and still don't recieve display. try to remove the video card and memory and clean it and re insert it. if still don't work. you got your motherboard defective.

As you say has become red and no power to the hard disk.First check the power cable for any loose connections and check if it give power to the cpu and the fan placed on processor starts working as you start the power. If fan it starts and with in few seconds stops then your power supply/SMPS is weak or damage. So replace it for proper working of your computer. And if after power on all fines but red led on monitor and no power to hard disk Try to replace the hard disk power cables because they are not working because of it no operating system is detected and led of monitor is red. After replacing hard disk cables hard disk starts working and still no display or red led on monitor check the vga cable for loose connection or replace it.If you are using vga display from graphic card try to get display first from onboard vga slot.After it your problem will disappear and your pc run smooth and fine.

Power-on sequenceThe power-on sequence is for the purpose of the printer initialization and checking for possible malfunctions.The following is the sequence from when the printer is turned on until it enters STBY mode.

Main motor failure detectionThe CPU determines the main motor failure, stops the printer, and notifies the formatter of errorstatus, when it encounters the following conditions.

Main motor start-up abnormality.

The interval of the MAIN MOTOR SPEED DETECTION signal (/MAINMFG) does not become the specified interval after 1000 ms of the main motor drive start.

Main motor rotation abnormality. The interval of the /MAINMFG signal stays at an irregular interval for 100 ms and longer after once it has become the specified interval.

Fan motor failure detectionThe CPU determines the fan motor failure and notifies the formatter when it encounters the followingcondition.The FAN LOCK signal (FANLCK) is “H” for approximately 10 seconds and longer during fan motorrotation.Your description makes it sound as though the printer has a main CPU failure as all other faults should display an error or error code. In the light of this it seems that the printer will need to be looked at by a service engineer asap.

memory is the main problem if you have two in two slots remove the one which is away from processor if no results remove both , clean the pins well and re insert.one // if no display remove and put another one ..it has to workif it doesnt then processor is heating up excessively because the cpu paste has dried up which is found between the cpu and heatsink fan

you have to narrow down the issue.. is it with the pc? or monitor? if you think the cpu... is the power supply fan working? is the cpu overheating? if you think its the monitor...be sure the card is seated properly and check all cables

cpu casing? What is that? To test the power supply, just use a paper clip in the ATX connector on the green wire, and the black wire next to it. Make sure everything that is hooked up to the power plugs, is unplugged. That should tell you if its the power supply.

Try having your battery tested. There may be not enough power to run everything on your comp.
Anotherthing to consider, if your CPU fan isnt working the bios wont start the O.S. as the CPU will overheat and shut down automatically. Good Luck
